It is accepted that industrial activity and the power sector are closely related. Industries use electricity supplied by Utilities through the grid network to power economic activity. While some industries use co-generation (as described in a previous blog) to power their operations, co-generation is not always viable. In a previous blog post, we reviewed the …

Cogeneration is typically defined as the sequential generation of two different forms of energy from a single energy source (Bureau of Energy Efficiency). This energy source can be fossil fuel or a renewable resource such as biomass. Cogeneration power plants have been in operation for quite some time in India. These power plants are used …

In a previous blog post, we shared our views on the importance of transformer testing and discussed: a) the principles of winding resistance measurement, b) OLTC condition analysis and c) our thoughts on the ideal kit for transformer testing. In this blog post, we will share our knowledge on assessment of possible winding & core …
In earlier blog, we discussed in detail a major problem plaguing the electricity sector in India – ensuring financial viability of Distribution Utilities (DISCOMs). We noted how this objective has long been a policy focus for successive governments and discussed a new Central Government scheme aimed at ensuring financial viability of DISCOMs; a scheme which …
In an earlier blog, we discussed the techniques and methodologies for health assessment of lightning/surge arresters. We also shared our knowledge on the various methods of measuring resistive leakage current or power loss. In the following blog, we answered the 10 most frequently asked questions on the various aspects of testing and measuring lightning/surge arresters. …

Over the years, power generation in India has grown manifold: installed capacity has increased from 1.36 GW in 1947 to 382.73 GW as on April 2021 (Source: CEA). Therefore, maintenance of generators is critical to ensuring uninterrupted quality power to the country. Apart from the generator, the HT transformer and the HT motors play a …

In our last blog post we spoke about the work done by our services division ISOSCELES Commissioning of PMUs for a Central Transmission Utility. On popular demand, today we are doing knowledge sharing on PMUs and WAMS as well as technical information on our offering of Vizimax PMU. Background The Indian Electricity Grid, following the …

Most of the Low-Carbon Technologies (LCTs) used today (mainly EV battery charging, rooftop solar systems and data centre loads) are all non-linear loads. Ohm’s law is not applicable to such loads, meaning that the current is not proportional to the voltage and fluctuates based on the alternating load impedance. Utilities face many problems as their …
High Voltage Circuit Breakers (HV/EHV/UHV) act as the most effective protection mechanism against electrical mishaps in the high voltage environment of Substations. Since Circuit Breakers (CBs) are mechanical devices, they are vulnerable to breakdowns if timely performance tests are not conducted to ensure their functional healthiness. In our earlier post, we broadly covered the 9 …
